y = -14/3x + 43/3
Step-by-step explanation:
y2 - y1 / x2 - x1
5 - (-9) / 2 - 5
14 / -3
- 14/3
y = -14/3x + b
5 = -14/3(2) + b
5 = -28/3 + b
43/3 = b
y = -14/3x + 43/3

Answers
Answer:
$90
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 9%/100 = 0.09 per year,
then, solving our equation
I = 2000 × 0.09 × 0.5 = 90
I = $ 90.00
The simple interest accumulated
on a principal of $ 2,000.00
at a rate of 9% per year
for 0.5 years is $ 90.00.
A school ordered 32 orange shirts, 29 blue shirts, and 34 green shirts. The shirts are being divided equally among 6 classrooms. If each classroom gets the same number of shirts, how many shirts will be left over?
A.
2
B.
4
C.
5
D.
3
Answers
Answer: D
Step-to-step explanation:
Answer:
C
Step-by-step explanation:
The orange shirts will have 32/6 = 5 with 2 left over
The blue shirts will have 29/6 = 4 with 5 left over
The green shirts will have 34/6 = 5 with 4 left over
The left overs are 2 + 5 + 4 = 11 but I have divided the colors equally. If color does not matter then the total number of shirts = 32 + 29 + 34
The total number of shirts is 95
95/6 = 15 with a remainder of 5
So 5 shirts will be left over.

What is the volume of a rectangular prism that has a height of 2 inches a width of 2 and 1/2 inches and a length of 5 and 1/2 inches?
Answers
Answer:
V = 27.4 in^2
Step-by-step explanation:
Converting to mixed numbers with fractions in decimal format makes this problem easier. 2 1/2 inches is the same as 2.5 inches; 5 1/2 inches is 5.5 inches.
The volume formula is V = L*W*H.
Here, V = (5.5 in)(2.5 in)(2 in), or 27.4 in^2
